IMPROVEMENT IN PLOWS.

To all whom it may concern:

Be it known that I, GEORGE W. Oo'oPER, of Ogeechee, in the county of Screven and State of Georgia, have invented certain new and useful Improvements in Flows; and I do hereby declare the following to be a lull, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure 1 represents a perspective view of the plow complete. Fig. 2 represents a vertical section through the mold-board to show the fastenings in rear of it. Fig. 3 represents another form of plow with a landside, which may be used instead of the shovel-plow.

Similarletters, where they occur in the separate figures, denote like parts.

The nature of my invention relates to the manner of uniting the handles and standard to the beam of the plow by means of a self adjusting joint, so as to admit of raising or lowering the plow and handles on the beam.

To enable others skilled in the alt to make and use my invention, I will proceed to describe the same with reference to the drawings. A represents the beam of the plow, to which the handles B are united by a bolt, a, so that said handles may slightly hinge or turn on said bolt, the ends of the handles where they are pivoted to the beam being caught in a clipwasher, b, to give them requisite strength and to keep them from wearing away.

O is the standard of the plow, which passes through therear of the beam A, where it is pivoted by a bolt, 0, on which the beam and standard may pivot or play when an adjustment of the plow is to be made. To the top of the standard 0 is pivoted one end of an arm, D, the other end being secured to the rung E by a. ferrule or broad band or ring, (I, so that the standard 0 and arm D, which unite the rear of the beam with the handles B, shall have an elbow-joint at e, as shown in the perspective figure.

Near the lower end of the standard 0 is an arm, G, curving upward and forward, and the point of the said arm G is hinged by a bolt-,f, to a stirrup, H, which passes over and around the beam A, said stirrup being provided with a suitable number of adj usting-holes, 1 2 3, &c., through which and through the beam a bolt, 2', may pass for adjusting and holding in adjustment the plow to the beam.

I is a mold-board, which may be of any of the usual forms, and is secured to the standard by means of a point, 5, shoulder 6, staple 7, and key 8, as shown in Figs. 1 and 2. When a landsideplow is used, such as represented in Fig. 3, or any other ot'the well-known plows, an extra standard, J, may be used, which is caught and made adjustable in the staple a on the side of the beam A for the purpose of ad ditional strength, and in this case, too, the plow comes t'artheri'orward on the beam, the standard 0 being united to the landside K by a bolt passing through a hole, at, in the rear of said landside, and another hole, 0, in the bottom of the standard 0, the key in this case being used behind the standard J when it is passed through the staple a.

The drag-bar 8 runs back underneath the beam sufficiently far to take the draft or strain at or near the center of motion of the plow,

and this drag-bar is made adjustable in a lateral direction at the point of the beam by a bolt passing through a plate, r, and through an eye in the drag-bar, the object being to adjust the run of the plow from or toward the landside, as may be required.

Instead of the arm D, two branched arms may pass from the joint 0, one going to each of the handles, and united thereto, instead of uniting by the rung E.

The operation will be obvious from the description, for when the plow is raised up or let down by the stirrup H and bolt i the standard swings at c, and the joint 0 is raised or lowered and takes up or lets down to the extent of the adjustment, while the handles, very slightly moving at a, maintain practically their same relative position in regard to the beam;

Having thus fully described the nature of my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

Uniting the handles of the plow to the standardthereot'bymeansottheself-adjustingelbowjoint 0, so that both the handles and the plow shall be susceptible of the same relative ad justment to the beam as described.
